摘要
为解决供水管网实时水力模型节点流量计算不准确的问题,提出了一种计算节点流量的方法。该方法通过供水管网GIS中的“水表上溯”来定位水力模型中的用水节点;通过营业收费数据来确定节点的平均用水量;通过现场测试和主成分分析法确定了19种用户类型及其用水变化曲线。同现有其他方法相比,其定位更准确,流量分配更符合实际情况,使大型城市供水管网水力实时在线模拟成为可能。
This paper presents a better method to determine node-flow in hydraulic model of urban water supply network. The node-flow in the model should be traced by means of ＂meter tracing＂ method in water supply network GIS, and the average node-flow could be calculated on the base of systematic database of water sale charges. 19 kinds of water users and its daily water consumption variance curves were classified by field survey and the main composition factor approach. Contrast to other existing water-demand computing methods, this method has advantages of accurate orientation and node-flow calculation, which make it possible to realize realtime simulation of large-scale urban water supply network.
